and includes features of construction which make
apparatus for that purpose.
The new token may be made oi various mate- .
rials and in different forms, although since it is
to be used in place of coins, it should be small
and compact, so that >it can be readily handled,
carried, counted, etc. In all for-ms, the token
includes a body which has a sealed cavity con
taining a material which has the property of
emitting light when subjected to the action of a
high frequency field, and the cavity 'is deiined in
part by one >or more walls which will transmit
the light emitted by the materiel within the =
cavity.

sealed together.l This rim maybe made of metal
or other suitable Wear-resisting material and it
serves to protect the sealed edges of the sections
and to prevent them from becoming chipped with
possible escape of the gas. The protective rim
may be given a distinctive color which serves to
distinguish tokens of one value from those of
another.
The token shown in Figs. 1 and 2 has a body
in which the opposite faces are flat and parallel,
but Yif desired, the token may be made of a pair
of sections 24 which are spherically curved.
These sections define a sealed cavity 25'contain
ing the gas ñlling previously described, andthe
united edges of the sections may be protected by
a metallic rim 2B generally similar to rim 23.
The body of the token, instead of being formed
of a pair oi sections sealed together along their
edges, may be made of a continuous glassV en
velope 21 formed in accordance with `conventional
methods, and then evacuated and given its gase
ous filling. The body so formed by glass blow
ing may have any suitable shape, but for con
venience in handling, it will preferably be flat
tened and of circular outline. The glass used
may be clear or `of a color that will modify the
light emitted by .the gaseous filling.

is made up of a pair of sections 32 of circular
outline, which have recesses of square outline
providing a square sealed cavity 33 when the
sections are secured together face to face. This
cavity, as in the other tokens, is ,ñlled with a gas
which glows when subjected to a high frequency
field.
In another modified form sho-wn in Figs. 8 and
9, the body 34 of the token may be formed of a
pair of united dished sections or of a single en
velope of suitable shape, this body containing a
sealed cavity for the gaseous lilling. The body
is protected by a shield 35 which serves the same

may be applied, as indicated at 46 to the inner
surface of the cavity, and by the use of a suitable
fluorescent material, lightfof various shades may
be produced by the action of a high frequency
field upon the token. The fluorescent materials
that may be used for the purpose are the usual
